HOW TO USE THE NEW BRADY SUPROPAQUE CORRECTION SEALS

Many who use Port-A-Punch cards for punching direct field records in
continuous forest inventory w ill be pleased to know that a new, improved
correction seal has been developed by the W, H. Brady Company, 727 W.
Glendale Avenue, Milwaukee, Wisconsin, 53209.

The new seal is more opaque, it is made of tougher materials, and it is
white on top and red on the lower or sticky surface.

This seal is superior for correcting obvious field Port-A-Punch errors
made in the course of setting out CPI plots. This procedure is desirable
where the field P.A.P. cards are reproduced to tape or to 80 -column cards

Certain precautions in the use of the Brady seal are suggested. Very
careful techniques must be applied in taking the seals from the portable
dispenser card, and in transferring seals to the top side of the
P.A.P. cardsl

Sketches on the following page demonstrate most of the flagrant errors
in the use of the seals. Recommendations for handling these errors
include the following:

Figure 1. Remove seals from the dispenser card one at a time. Use

,P.A.P. jstylu£ to pluck the seal from the card. Use care,. ..

Do not puncture or bend the seal. Press zip strip back
against the remaining unused seals.

The adhesive on the red side of the seal will hold it fast
to the stylus. Roll the stylus back away from the seal
when it is placed properly over the hole in the card.

Press seal down firmly on P.A.P, card.

Figure 2. Press seals flat on P.A.P. card. Do not wrinkle.

Figure 3* Place seals over P.A.P. car'd holes squarely with edges
of the card. Cover only one hole with each seal.

Figure h • Be sure to cover the hole completely. Do not leave open
edges or corners where the light shews through.

Figure 5« Do not overlap correction seals, or machine may jam.

CAUTION: The seals should be kept free of mosquito dope, especially
in hot weather, for under these conditions the adhesive may seep out
from beneath the seals and two successive P.A.P. cards tend to stick
together. This causes machine trouble when the cards are reproduced
or placed on tape.

Excess adhesive may be removed from the two adjacent cards with an
ordinary lead pencil eraser, or an occasional sticky P.A.P, card may
be repunched to handle the problem if it occurs.

A MESSAGE ON THE CFI SCHOOL PAPERS

The proceedings of the spring CPI school have been
delayed. Everybody has printing to do at Michigan
Technological University. Our school papers must
await their turn in the press. We promise, though,
that they will be out late in the fall, complete
and full of fine words and ideas, all of which
have just one purpose; a better understanding of
the forest so that it may be managed in complete
conformity with the guiding rules and limitations
of Nature for the continuing good of man.
